spective view of a modified form of closure shown in Figs. 9,-10, and11. p

In the drawings 1 represents a. pressure tank and 2 a. vacuum tank whichare piped respectively to the pressure and exhaust cylinders of a doublepump '3 operated by a motor 41-. or any convenient means commonly used.such as continuous water vacuum inspirators or the like. An air Washer,filter and sterilizer 5 of anyapproved. type is interposed between thepressure mechanism and tankl in the supply pipe 6. As herein shown, thisconsists of an outer air tight cusin 8 partially filled With water orpreferret sterilizing and Washing fluid into which an air inlet. pipe 9discharges and a. cage 10 into the top of the casing. having aperforated bottom 11 supporting a filter bed 12 of any material desired,through which th air is forced into an outlet 13 in the top of the cage.pump or the like is arranged. to take air from a. point remote from themilking room or station.

The pressure and vacuum tanks are each provided with pipe lines l5 and16 which extend to the various milking: stations Where suitable coclts17 are plziceil' :ior ten'iporarily connecting the pulsators andeerators.

The juilsatoiyand seuitor consists of a metal plate '18 adapted todetuchahly engage and soul the mouth of uniilk receptacle or can it). Avalve casing 20 secured on the plate has a cylindrical coun'terhorecichanr her in which the body of e rotatable e? lindrical valve closure 21is eceentricsl. y journalech having u pair of spring projectedahutinents 2'12- plnyin in tliuinetrical sloT; that yieldingly svve thecasing "Null anti divide the ch'sinher into two coni'purt; ments ofvariable size its a tile ii. of construction, flange 24 ne rorinetl onthe lower end the hhdv .vi'th 1* slot or;- tenilingheyond the boil-yinto the flange so as to allord support to the ahutinents throughouttheir length beyond the body of the closure itself. An inlet port 22-5in the chamber wall connected l3}; a duct 26 QB ceases v p discharges Vi lly preferably neap th center.

Milk assages 30, of any desired number, preferably formed in ribs 81cast upon the plate, extend from the periphery so as to dischargevertically ontoa distributing cone jam nuts 34: on the bottom of astrainer 35 32 supported on a stem 33 secured as by of Wire gauze orperforated-metal attached at its upper end to the underside of the plate18. The outer portions of. the ducts are counterbored and the wall outawayto receive glasses 36 which may conveniently of the system throughan exhaust 58 in the be secured therein between gaskets 37 by valves 38screw-threaded into the outer ends and connected hyiiexible tubing 39with a multiple connection. The latter preferably consists ofan ovalcasing lO having a tube receiving nipple ll at one end and a plug 42 at'the other frictionally engaged so as "to be readily removed forcleaning purposes.

Stop-cocks l3 are secured. in the casing and are connected by shortflexible tubes at with elongated nipples 45 which are slightly collapsibleunder pressure and are adapted to close over. the teats of ananimal. The receptacle is connected to the vacuum tank 2 plate 18vproperly fitted for the usual pipe or .hose connections.

In operation, the plate is placed on a can and'connec'ted with thepressure and vacuum pipes as described and with thenipp'lcs adjusted.Thereafter the operator, by opening the regulator valve after the can isex hausted, and admitting the compressed air I milking room or stationand washed, cooled and sterilized as shown. Thus the milk is deliveredthrough 'the strainer ready for the dai i 1 die of the features of theinvention is the adaptability and adjustability of the apparatus for anyplace, as the proper arrangement of the main line piping is all that isnecessary to meet any requirement of service;

Another feature isthc purification, cooling and aerating of the milk asdelivered, by air which is drawn from without the place i where theanimals are being milked, thus eifectually preventing any absorption ofob jectionalole odors, While the bulk of the portable parts is notincreased.

A further and important feature is the positive, automatic action of thepulsator, and its'instantaneous response when the reg ulator'valve isopened, without the use of mechanism to operate the closure,'thedisposition of the ports preventing the'closure from becoming-set on adead center. The

single rotating member is completely housed and shielded from dirt,requires no ad ustment when once operatlvely mounted, and 1s noiselessin action. The regulator valve controls it absolutely and its speed isreadily varied thereby. There is no external mechanism whatever and thesharpness and regularity of the-pulsations obtained insures theproperaction of the nipples.

Where the system is extensive, the Work on the compressor and vacuumpumps maybe lessened by-introducing the compressed air directly-to eachpipe leading from the-nip? ples to the pulsator, by arranging the parts5 as indicated in Figs. 9,10 and-l1. Lateral milk passages 47 are formedin suitable lugs in the air valvecasing 48 which meet at'a centralvertical duct 49 discharging through the plate. into the deflector andaerating ,9

strainer 50. The casing is 'counterbor'ed and fitted. with a closure 51and abutments 56 as in the first construction, but the flange 53 of theclosure is extended so as'to cut oft the duct 49 at the same tinie that,thehbuts 5 ments are admitting compressedair through a discharge 54into the milk passages, and periodically open the duct 4am otherlines,this being effected by cutting gains ;or ports in the margin of theflange 53in proper timed relation to the abutments 52 and their ports.Thus the space in which the vacuum is to be relieved requires a lessamountof compressed air and less work of the vacuum pump to obtainproper results.

Obviously other changes in the details of construction may be madewithout departing from the spirit of the invention and I do not care tolimit rvself to any-particular form or arrangement; of parts.
